Technical field
The present invention relates to a kind of method of automatic cutting-off process of the internal-combustion engine that is used for the controller motor-car by claim 1 as described in the preamble.
Background technique
Several different methods and system have been developed in order to reduce oil consumption and discharge of poisonous waste now, their parts also come into operation, these method and systems are at the internal-combustion engine of automatic cutting off table motor-car under some precondition or when having predetermined cut-out condition, and connect the internal-combustion engine of Motor Vehicle when having predetermined on condition again automatically.Such method and system or startup-arresting stop mainly are applicable to urban transportation so that reduce oil consumption, because often run into traffic light or owing to traffic is stopped in urban transportation, and internal combustion engine operation is optional.
Therefore by known a kind of the stopping automatically and the start-up control device of internal-combustion engine that be used for of DE 101 61 343 A1, wherein control gear implements to be used to cut off the corresponding measure of internal-combustion engine, satisfies the cut-out condition that all are enumerated this moment.For example car speed must be less than a predetermined threshold value, do not allow to hang gear in manual transmission, and the drive range of speed changer must be on neutral gear position in the automatic transmission vehicle.
Yet may occur in some cases, though the driver wishes to cut off automatically internal-combustion engine, and implement all essential operations for this reason, this is owing to the precondition that lacks system aspects is impossible.Therefore DE 100 30 290 A1 disclose a kind of method and system that is used for cutting off automatically and restarting internal-combustion engine, wherein, when the charged state of Vehicular battery when a predetermined threshold value is following, prevent automatic cut-out.
In addition, when may with great possibility set out in, when whether relating to that automatic or traditional manual startup is irrelevant can not the enforcement of no problem ground restarts, should under any circumstance prevent to cut off automatically internal-combustion engine.If cut off internal-combustion engine and then can not restart the time, this may cause the client to complain.
Summary of the invention
The objective of the invention is, a kind of method that is used for the automatic cutting-off process of controlling combustion engine is provided,,, prevent to cut off automatically internal-combustion engine when being starting point can not no problem ground to restart with very big possibility by this method.
Described purpose solves by a kind of method by claim 1.Favourable further expansion is provided by dependent claims.
The present invention is based on following knowledge, promptly because the defective of the miscellaneous part of starter or start-up system or (starter) battery status (that for example damage or empty battery) can not start this internal-combustion engine by vehicle-mounted starter, but because distraction procedure starts this internal-combustion engine, then should not cut off internal-combustion engine automatically, because perhaps can only restart by traction again.Therefore the driver does not wish to cut off automatically internal-combustion engine.
Basic thought of the present invention is, must prevent to cut off automatically internal-combustion engine when the internal-combustion engine that starts owing to distraction procedure.Characteristics by the method for the automatic cutting-off process of the internal-combustion engine that is used for the controller motor-car of the present invention are, when in the circulation of travelling at this promptly when manually implementing to pass through the distraction procedure starting apparatus combustion engine in the cutting-off process of internal-combustion engine or the circulation of carrying out before this of travelling next time at predetermined quantity, prevent to cut off automatically internal-combustion engine.
Advantageously prevent to cut off automatically internal-combustion engine in the following way, even implement to cut off automatically the disabler of internal-combustion engine, this function can be the part of so-called " start automatically and stop robot device " or " mixed control unit ".The advantage that inefficacy brings is both to have made because wrong function for example owing to wrong signal analysis, can not implement to cut off automatically internal-combustion engine in the time limit of losing efficacy.In addition, whole system was lost efficacy and cause reducing load (being fully loaded with of processor or storage).
Advantageously by surveying and the mobility of analysis description starter unit and/or the traction of inactive signal identification internal-combustion engine.In a kind of favourable mode of execution of the present invention, after recognizing successfully starting apparatus combustion engine, the mobility of describing the starter unit and/or inactive signal when the start-up course of internal-combustion engine begins not show the mobility of starter unit, then recognize the traction of internal-combustion engine.Therefore when lacking starter control, infer the startup that causes internal-combustion engine owing to external action by exclusiveness, and forbid the automatic cut-out of internal-combustion engine.
Advantageously, when the importing that recognizes start-up course, and when when start-up course finishes, for example recognizing the revolution upper punch (Drehzahl ü berschwinger) of crankshaft revolution, then recognize the successful startup of internal-combustion engine.(success) start-up course of internal-combustion engine, i.e. the transition of the motor from static motor to running can be passed through the signal of the mobility of analysis description internal-combustion engine and for example discern by analyzing crankshaft revolution.When this external start-up course finishes by occur and detectable revolution upper punch and/or reach the successful startup of identification by the idling revolution.This identification that success starts can be carried out validity check by the analysis in time window in its time course, and improves by additional timing and the anti-mechanism of quivering.
When start-up course is proved to be the startup of success, advantageously for a preset time window or be the revolution that internal-combustion engine is predetermined, the mobility of the starter unit of internal-combustion engine and/or inactivity are by analyzing mobility and/or inactive signal verification of the starter unit of describing internal-combustion engine.Advantageously constitute mobility and/or the inactive signal of describing the starter unit, so that when recognizing the mobility of starter, its state is become " activity " by " inaction ".Signal preset time at interval and analyze the back or arrive start finish and when analyzing from " activity " state restoration to " inaction " state.Final condition as success is drawn except the inactivity of starter when starting beginning, also must start to finish produce successfully and draw by identification, only in this way draws to allow to be evaluated as success.
Except preventing the automatic cutting-off process of internal-combustion engine, when the traction that recognizes internal-combustion engine, also can implement other measure aspect the method for operation of internal-combustion engine or whole car, they are used for improving the method for operation at the trailed vehicle that has internal-combustion engine.
When Motor Vehicle for example is equipped with the hybrid drive unit that is made of internal-combustion engine that is used for the driving machine motor-car and motor, for example meaningfully, when recognizing the traction of internal-combustion engine, for example, stop to drive to switch to motor (that is to say stopping automatically of internal-combustion engine) from internal-combustion engine because start-up system is damaged.Therefore prevent motor vehicles parking after driving switches to motor from internal-combustion engine, because start-up system is also because its defective no longer can starting apparatus combustion engine.Therefore it is impossible restarting internal-combustion engine.There is the danger of " blocking ".
To sum up confirmablely be except making the disabler of implementing to cut off automatically internal-combustion engine, can introduce additional various measures when being pulled recognizing internal-combustion engine, thereby so that avoid so-called " blocking ".Therefore can avoid insurance premium and client complaint.Parts that separate in this external trailed situation or subtense angle can start when " urgent operation " of protectiveness or suchlike state, so that avoid possible malfunctioning.
Description of drawings
Explain by method of the present invention in detail by means of embodiment now.In case unique for this reason accompanying drawing makes the simplified flow chart of implementing the disabler that internal-combustion engine cuts off automatically when the traction that is used for recognizing internal-combustion engine is shown.
